   What is a chain hoist?
   Answer: Hand hoist is a simple and easy-to-carry hoisting machine, and it has also become a "chain hoist" and "inverted chain", which is widely used in various types of lifting environment.
   What should I pay attention to when using chain hoists?
   Answer: Pay attention to the following points when using chain hoist:
   1. The appearance inspection should be performed before use to see if the structure is complete, whether the rotating part is flexible, and whether the oil-filled part is oily, to prevent the occurrence of dry grinding and chain shifting in the chain hoist during use.
   2. The rope, bracket and cross beam of the hook and chain should be absolutely stable and reliable. After hanging, first pull the hand zipper back to loosen the chain to reach the required lifting distance, and then slowly pull the manual Chain, lifting heavy objects.
   3. When carrying and using an inverted chain, do not throw them around, to prevent other debris of the pulverizer from rotating inside the bearing, which will affect the service life.
   4. For chain hoists that have been used for more than 3 months, they need to be disassembled, inspected, cleaned, and oiled. For missing parts, malfunctions, and structural damage, you must continue to use them after repairing them.
   Why must I use an intact chain hoist when lifting heavy objects?
   Answer: If the hoist fails, it will cause injury to people.
   How should the hoist be stored and marked?
   Answer: If the inspection is qualified or unqualified, it shall be stored by area and clearly marked.
   Why can't I pull the chain with too much force?
   Answer: When operating the chain hoist, the force of pulling the chain should be uniform, the speed should be moderate, and it should not be too fast to prevent the hand zipper from grooving and jamming the chain.
   Why should the direction of the zipper be the same as that of the sprocket when operating the chain hoist?
   Answer: Regardless of the operation of the chain hoist in any direction, the direction of the zipper must be the same as the direction of the sprocket to prevent the hand zipper from falling out.
   Why can't I increase the number of people violently when the hoist is unable to move?
   Answer: When pulling the chain hoist, the cause should be found out, and the number of people cannot be arbitrarily increased to prevent accidents caused by overloading.
   Why do I have to fasten the hand zipper to the lifting chain when the hoist is stopped?
   Answer: If the hoist during lifting stays for a long time, you should fasten the hand zipper to the lifting chain. This is to prevent the self-locking failure from falling.
   Why can't at least two people use the hoist to lift large pieces?
   Answer: This is to prevent the chain from twisting abnormally and prevent large pieces from losing control due to missed hands.
